PPete483 replied to the thread High quality accelerator pump?.All I know about the power valve is that it is turned "off" when the plunger in the top of the carb is pulled up by vacuum and "on" when the vacuum drops and the plunger falls, so it should be off at idle and on at higher power. I've seen from...

PPete483 replied to the thread High quality accelerator pump?.I don't recall it looking too bad, but haven't had it apart in a while. The outside isn't paricularly rusty. Everything seems to repond as it should when I do the lean drop procedure. I'll try to the get the accelerator pump working and take...

PPete483 replied to the thread High quality accelerator pump?.I have no clue on the history of the carburetor, but this thing is a former Nicaraguan farm truck so it is safe to say whatever the worst thing that could have happened to it has probably happened.

Are you saying I should be able to start the truck just fine in sub-freezing weather without an accelerator pump? I'm also not sure what you mean about opening the...

PPete483 replied to the thread High quality accelerator pump?.The GP Sorensen kit came with a leather one, but it was a super cheap kit at the time, so I can't imagine it was the highest quality part. My diagnosis of the pump was that the truck starts fine as long as the temperature is above 50ish and that...

PI set about to diagnose my difficulty in cold starting my 1977 FJ45 and as I suspected, the accelerator pump is no good. I rebuilt the carb quite a while back with a cheap GP Sorensen parts kit and while everything else is fine, the accelerator...
